I am building a another Hemi engine and this time would like to add a little more compression. I want to still run pump gas (91 octane). Its for my Original Doodlebug.
Here is my setup.....
ARC flywheel
Black mamba Jr cam
26lb springs
gx140 emulsion tube w/Jets
Intake
Under Seat Header with RLV Muffler
Stainless Stock sized valves
Colder Plug
No porting or polishing head
Governor Removed
TAV2 w/11t/60t
To get more compression would I....
Mill the head if so how much?
.010 head gasket
ARC .020 over rod (Assuming there is room)
